PACKING FOR METALLIC BOXES.

SPECIFICATION forming part of Letters Patent No. 404,700, dated June 4,1889.

Application filed March 15, 1889.

To all whom it may concern:

Be it known that I, HENRY R. GILLINGHAM, of Baltimore, in the State ofMaryland, have invented certain new and useful Improvements in MetallicBoxes; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it pertains to make and use it, reference being hadto the accompanying drawings, which form part of this specification.

My invention relates to an improvement in packings for metallic boxes;and it consists in an oil and water proof packing composed of corkground in oil, then formed into sheets, and backed by a sheet of canvasor other strong fabric, as willbe more fully described hereinafter.

The object of my invention is to provide a packing which is oil andwater proof, and especially adapted for use in cans designed for packingliquid paint and pasty matters, so that all necessity for soldering onthe tops of cans is done away with and the cans made perfectly tight bymerely screwing on their covers.

Figure 1 is a vertical section of a box or can which embodies myinvention. Fig. 2 is a plan view of the packing-ring.

A represents a metallic can or box, of any desired shape or size,screw-threaded at its top Serial No. 303,428- (No model.)

porting-flange B at its top. The screw-threaded cap 0 snugly fits uponthe top of this can and forms an absolutely-tight joint against oil andwater by means of the ring-packing D, which rests on the flange B.

The packing is composed of cork, which is ground to a suitableconsistency in linseedoil, then formed into sheets of suitablethickness, and backed by a sheet of canvas or other strong fabric, whichis cemented thereto. The cork and oil are impervious to oil, whichwillreadily dissolve or permeate rubber and other such packin gs, andrenders the cans or boxes perfectly safe for packing or carrying oils,paints, or other substances. This packing is specially adapted for theseboxes or cans, and has a greater value in this F connection than anyother now known.

Having thus described my invention, I claim A packing for cans providedwith screwcovers, and for other vessels of capacity, composed ofcomminuted cork saturated with linseed-oil and provided with a backingof canvas, substantially as shown.

In testimony whereof I affix my signature in presence of two witnesses.

HENRY R. GILLINGHAM.
